Stamina/Aerobic exercise
Building stamina and endurance with aerobic exercise does not have to be intense and exhausting. There are different forms of exercise that will allow you to improve your stamina. You could simply walk 30 minutes on your way to and from school. Cycling there and back could also be an option. If walking and biking are too easy, you could jog. If you like to swim, you can do laps at the swimming pool and try various styles. If you have access to a park or mountain, you can ski in the winter and try more challenging trails when you feel ready.

To strengthen your muscles and work on your stability, you don’t necessarily have to go to the gym. Simply carrying your school bag or grocery bags are muscle strengthening exercises. You could also easily do push-ups and crunches at home.
